problem #2

From the day one, during the first 25 minutes of driving, my new 2012 mb ML350 vibrates and make grinding noise just in between 40 to 45 miles per hour steady driving. After about 30 minutes of driving, the vibration and the noise are not noticeable. Mb and the dealer were trying to fix the problem but failed to resolved the problem. Now, they have concluded that the vibration is normal and is characteristic of the car. Any problems mb can't solve is normal!! what kind of car is it that vibrates for first 25 minutes of driving at certain speed is normal!!

Oil was leaking from the engine which was the result of a faulty part that Mercedes has subsequently replaced with a new re-engineered part. The dealer indicated that the issue is systemic with all blue-tec M and G class vehicles which Mercedes will not cover the charge for. The repair requires that the engine be removed from the car because that it is the only way the part ($30) can be replaced. The resulting repair cost over $1900 in labor. We noticed the leak because there was oil drips in our garage. The service technician at the dealership noted that we had lost about a third of our oil and that the oil was covering the engine and it was also noted that the oil could have caused a fire if the part was not immediately replaced.
